 1) Installer CD Boot Code
 A default.xbe has to be added to the installer CD and the CD has to be
 in hybrid UDF/ISO9660 format. The Xbox bootloader loads the standard
 kernel, which has Xbox support compiled in, as well as the standard
 ramdisk. Just default.xbe instead of El Torito  SYSLINUX.

Adding UDF support does not bring any trouble, but regarding the boot
method, does that mean that the Xbox just ignore el torito and
syslinux boot option, and that just putting the default.xbe file
on the CD root is enought, or do we need to have 2 different boot CDs ?

Originally, we had an additional partitioning module in the kernel for 
Xbox partitioning. Now our code makes it possible to use both 
partitioning schemes in parallel: The PC partition table is read first, 
and the Xbox partitions (which may of course overlap) will be added 
after the PC partitions, in the /dev/hda? numbering. This way, the user 
can access the Xbox partitions, and can partition the free space on the 
hard disk (the space above 8 GB; we can use replacement hard disks; the 
Xbox kernel only uses 8 GB) using a PC partition table.

 Booting from HD works like this:
 If there is no bootable media in the Xbox DVD drive, it starts the 
 file
 xboxdash.xbe from the fourth partition on the hard disk, which is a 
 FATX
 filesystem. We could make Mandrake mount this partition as /boot, as 
 it
 contains the kernel and the initrd; and it will also contain 
 xboxdash.xbe,
 which is our bootloader.

 that means /boot will not allow symlinks?

Not at the moment, just as FAT, but we're working on a compatible 
extension of FATX to allow symlinks and everything, just like UMSDOS.

 some code in the installer used to allow this (for the time when we
 configured loadlin only), but i don't know if it still works nicely.

 what is the format of the config file? lilo-like?

Its format is compatible with GRUB  SYSLINUX. It looks about like this:
kernel boot\vmlinuz
initrd boot\initrd
append root=/dev/hda2
it can also look like this:
kernel boot\vmlinuz initrd=boot\initrd root=/dev/hda2
Note that the bootloader runs in the Xbox kernel environment, which is 
basically an NT environment, so the partition names differ, filenames 
are case insensitive etc.

 hint for the code, file bootloader.pm:

 - function suggest: decides which bootloaders are allowed (search 
 yaboot)
 - functions install_*: install the bootloader (beware install_silo is
 not a good example and may be outdated)

Thanks, I'll have a look at it.

 hint for the code:

 - partition_table::read_one tries to recognize the partition table type
 - it uses partition_table::*::read which detects the partition table
 - the various partition_table/*.pm inheritates from 
 partition_table/raw.pm

Thanks.

 3) XFree Configuration
 The XFree configuration program has to write its own XF86Config-4, if 
 we're on
 an Xbox. Well, perhaps the standard routines will work out of the box.

 it should :)

Oh, I forgot: On the Xbox, there has to be an additional section in 
XF86Config-4 that makes XFree turn off the PCI scan, because this would 
lock up the machine because of its PCI bug.
And only framebuffer works so far.

Re: [Cooker] Xbox Linux support for Mandrake

2002-10-11 Thread Michael Steil
Originally, we had an additional partitioning module in the kernel 
for Xbox
partitioning. Now our code makes it possible to use both partitioning 
schemes in
parallel: The PC partition table is read first, and the Xbox 
partitions (which
may of course overlap) will be added after the PC partitions, in the 
/dev/hda?
numbering. This way, the user can access the Xbox partitions, and can 
partition
the free space on the hard disk (the space above 8 GB; we can use 
replacement
hard disks; the Xbox kernel only uses 8 GB) using a PC partition 
table.

If we can avoid overlapping partition, this can be fine (else user may 
do
dangerous things).

If the partition are not complicated (?), we can add the native support
directly so that the first 8GB will naturally be reserved instead of 
hacking the
current partition scheme used for PC.

The problem is that the Xbox has no partition table, the partitioning 
is implicit. It looks like this on all boxes:
1: 0.5 - 750.5 MB (temp 1)
2: 750.5 - 1500.5 MB (temp 2)
3: 1500.5 - 2250.5 MB (temp 3)
4: 2250.5 - 2750.5 MB (boot)
5: 2750.5 - 8 GB (data)
We cannot change this partitioning, the Xbox system software always 
uses this table. Of course we could extend the partition table: We 
could add an additional partition table at 8 GB with the partitioning 
information for the space above 8 GB.
Because it was quite easy, we used the PC partitioning system in our 
current versions; the first sector on the Xbox HD is unused anyway. The 
user just had to avoid partitioning any of the space up to 8 GB.
We're not certain yet how to handle this. Our Xbox Linux Mandrake 
installer marks the space up to 8 GB as partition 4, and the user is 
free to create partitions 1 to 3 and 5+ in the unallocated space. If 
the installer (and command line fdisk) were extended to mark the space 
up to 8 GB as unavailable if it's an Xbox drive, this would be the most 
beautiful method, I think.

We don't have Xbox here so you will have to provide information on 
how to

[Cooker] Xbox Linux support for Mandrake

2002-10-10 Thread Michael Steil

Hi!

I am Michael Steil from the Xbox Linux Project. I have had a 
conversation with Gael and Jacques from Mandrake and I was told that 
they don't officially support Xbox Linux, but they support it 
non-officially. Jacques suggested to discuss about this on this mailing 
list.

As you might already know, the Xbox Linux Project succeeded in running 
a full Mandrake distribution on a modded Xbox console; we just had to 
use an installer of our own because of some differences in the Xbox 
architecture.

Me personally, and probably some others from Xbox Linux would like to 
extend our work to integrate full Xbox support into the next Mandrake 
release. Therefore we ask for some support in this mailing list, and we 
might have to discuss some things on how to integrate Xbox support.

Some information about the differences of the Xbox:

The Xbox is basically a PC, but with some small differences:

1) Kernel fixes: PCI bug, different timer base frequency, different 
shutdown method, no keyboard controller
These issues are already addressed by our kernel patches and they are 
likely to be included into the main Linux kernel soon.

2) Kernel/driver extensions
We have code for the FATX file system used by the Xbox system software, 
as well as drivers for the Xbox gamepad and the Xbox remote control.

3) Different boot method
The Xbox needs the boot CD to be in UDF format (that's easy with 
mkisofs -udf) and the bootloader called default.xbe in the root 
directory of the CD. This bootloader has been developed by the Xbox 
Linux Project and boots Linux just as Grub or LILO.
When booting from HD, the bootloader executable and the kernel have to 
be stored in a FATX file system.

4) Different HD partitioning
The Xbox uses an implicit partitioning scheme, but we can also use the 
PC partitioning scheme in parallel.

5) XFree
Currently, only Framebuffer is supported.

So we basically have a patched kernel, some more modules and a 
different bootloader. So what do we have to change in the Mandrake 
installer?

1) Installer CD Boot Code
A default.xbe has to be added to the installer CD and the CD has to be 
in hybrid UDF/ISO9660 format. The Xbox bootloader loads the standard 
kernel, which has Xbox support compiled in, as well as the standard 
ramdisk. Just default.xbe instead of El Torito  SYSLINUX.

2) Partitioning Tool
The partitioning tool has to mark the space used by the Xbox system 
software as unavailable (if we're on an Xbox) for the user not to 
overwrite the original software on the HD and render the Xbox useless

3) XFree Configuration
The XFree configuration program has to write its own XF86Config-4, if 
we're on an Xbox. Well, perhaps the standard routines will work out of 
the box.

4) Bootloader Installation
If we're on an Xbox, the grub/LILO installation has to be replaced by 
the Xbox bootloader installation.

5) Kernel, /lib/modules
The standard kernel has to include the Xbox fixes; one kernel for both 
PC and Xbox will be enough.
The Xbox modules for FATX, Xpad etc. will be added to /lib/modules on 
all machines.

It's not that much. I'd love to help adding Xbox support to the 
installer, and we can provide patches for the kernel to add Xbox 
support in the kernel to Mandrake.

 The Xbox uses an implicit partitioning scheme, but we can also use the 
 PC partitioning scheme in parallel.
 
 5) XFree
 Currently, only Framebuffer is supported.
 
 So we basically have a patched kernel, some more modules and a different 
 bootloader. So what do we have to change in the Mandrake installer?
 
 1) Installer CD Boot Code
 A default.xbe has to be added to the installer CD and the CD has to be 
 in hybrid UDF/ISO9660 format. The Xbox bootloader loads the standard 
 kernel, which has Xbox support compiled in, as well as the standard 
 ramdisk. Just default.xbe instead of El Torito  SYSLINUX.

make two sets of iso's, one for pc and one for xbox? 694 mb iso can't be 
dual fs on 700 mb cdr can it?
 
 2) Partitioning Tool
 The partitioning tool has to mark the space used by the Xbox system 
 software as unavailable (if we're on an Xbox) for the user not to 
 overwrite the original software on the HD and render the Xbox useless
adding the fs option to the patritioning tool(s) should be fairly 
simple, since you obviously have the code to do so.

 
 3) XFree Configuration
 The XFree configuration program has to write its own XF86Config-4, if 
 we're on an Xbox. Well, perhaps the standard routines will work out of 
 the box.
 
 4) Bootloader Installation
 If we're on an Xbox, the grub/LILO installation has to be replaced by 
 the Xbox bootloader installation.
 
 5) Kernel, /lib/modules
 The standard kernel has to include the Xbox fixes; one kernel for both 
 PC and Xbox will be enough.
 The Xbox modules for FATX, Xpad etc. will be added to /lib/modules on 
 all machines.
 
 It's not that much. I'd love to help adding Xbox support to the 
 installer, and we can provide patches for the kernel to add Xbox support 
 in the kernel to Mandrake.

You have to use a modchip to allow the XBox to run code that's not
signed by MS.

 does this support the games that are written for the xbox?

AFAIK, it does not... you can still play XBox games normally, but you
cannot run them from within Linux.
